To all whom it may concern:

Be it known that I, FELIXBENEDlU'T Henzoo, Ph. D., a citizen of theUnited States, and a resident of the city, county, and, State of NewYork, have invented a new and use" ful Improvement in Electric SignalingApparatus and Circuits, of which the following is a specifintion.

My invention, in its fullest embodiment, consists in means for signalingfrom various floors of o,b11ilding to two or more elevetors in such n.manner that theeondnot-or of each car is informed whether the Waitingpassengegmzishes to go up or down, and also whether any other conductorhas on Led the call, {ind-it also enables each cofriouotur to signal tothe Waiting passenger that conductor is about to respond to the l ntion, and also enables eeeh conductor to dicote to the other conductors.

Inthe drawings Figurel is at rear w of the operating parts of thecalling box at the stations or floors; Fig. 2is a side sectiomend Fig. 3o front View ofthe seine. Fig. 4: is a general diagram of the circuitarrangements and the general organization of the system. Fig. 5, asimilar diagram, the individual circuits being multiplied as they wouldbe in a system using four buttons. Fig. 6 is n detail of theshort-eireuiting hell oi the Well known type, and Fig. 7 shows detailsof the box shown in 1 and 2.

Referring to the figures in cletnil:--ln Figs. 1, 2, and 3, a chlplieotearrangement is shown; the ports of the Up and Down buttons, respectivelybeing similar. The corresponding parts on the lower box bear the same"letters those on the upper but have a prime :1 ddecl thereto. In thedescription a port will he mentioned either with or without the primeaccording to which View of the partreferred to is most e: sy to find. Bypushing either button part lrl fixed to shank P is brought into Contactwith the Contact spring E, which normally rests in position against aninsulated pin, 0. Fixed to the shank is the cum with two ends, the oneenclli, preferably making the contact with F when it is notconi'enienttobore this made directly by the shank P, and the Second end X acting tolook the button in its depressed. position henever a current. throughmagnet M holds the armature E against the poles. The iii-mature or aneye tension shows through the window in the front plate in such :1inanner that its posi tion or its changes of position may be observedfrom the front of the box. In the Up part of the box the armature fallson 2 common to the general feed wire 19 (s wzuin heavy lines}. Tlheother feed wire or pole connects to this first wire by the res eetiveindividual or floor Wires-f ojoown in multi lie in Fi 5-there bein 75 to7 V t! one of these for each button, and. th ae end for eachbutton----ou top of the insulated stud T for the down and T for the upcells (Fig. thence go to spring 0 (or C}, magnet, and. contact cult iscompleted on that particular button is pushed. Spring C is fixed to aninsulated block arranged in any suitable innuner. in Fig. if the shapeof spring l is changed so on to make theillustrntion 85 elenreiz Theindividual wire for enrh hutton ends in 1: spring I? after passingthrough its .ningnet; hence, when the button is pressed and current isin line, :1 Contact is parts (including the frame s in any box, and. inoil} of the boxes they spring F where the cir made at l and currentthrough he magnet will reuse the armature to stick to the poles of M andwill thus cause the button to non tinue the oontiurt until uirruit isbroken at the distant siui'ion, whereupon the :umuturo permits thespring 5,: in res-lore the button 95 contact.

It

evident that with suilicient current any.

" to the operator whieh button it was that has been depressed andconsequently which floor has eigjmiled. each annunciator indicate torscorresponding to a given button sl1oul.d be located in a similarposition and the c0rnaroondinelj cut-ou switches should for connience beplaced in close proximity to the "indicator of the line to which theybelong.

is obvious that in the form selected for illus ration every indicator inseries on a wire will. operate simultaneously, and therefore everyconductor would siinultaneouslv linow that a given. button had beenpushed;' for instance. thelmtton'on. the (3th lioor marked to irulicatcthat a. passenger wished to be taken up. But it. is not ueceaeary thatall conductors should respond, and the conceit would be in a positionwhich would make it proper that; he should he the n to take a passengerunder those conditions would therefore ordh'iai'ily be the only fnoperone to respond, whereas the conductor or eomluctors oi the other car orcars, although they would know that a call had oer-u sent from thatpoint. by a passenger wishing to go in that direction, would disregardit Ililltf-HS they had reason. to believe that the conductor whose dutyit was was not in a position to perform that. duty, or had neglected it.in (other .vords--it is, of course, obvious that there no intention ofhavi more than one car stop to take one passenger. who has signaled:trom. a given floor, the intention being to eecure as the final resultoi the operation of the organization an a whole, and by wljiich all theears receive the signal, that which is set forth in the printedinstructions to the aiting pas--' senger which are ordinarily displayedon the front of the floor box in the manner shown in the illustrationThefirst car to its normal condition 'tion,un'der stressof the that passesin the direction indicated will stop for you. By giving the required information 5imultanemisly lo'all cars the result is secured that it thefirst car about to pass in the desired direction should not be availableFor any reason, as, for instance, should be moving at such speed asnotio be able to stop in time, or should be too full, the next car couldrespond and thus the passenger can give the effective notice inconnection with a group of cars, by the act of operating one signal onlyas against the necessity of operating one tor each car as it. existedbefore my invention.

During the entire time that the indication corresponding to any floor isthus displayed in the cars, the corresponding button remains held inplace as the result of the magnetic clutch. described. The properconductor as soon as he \viahes to respond gives a tap upon the buttonof the cut-out switch, 14-, thus opening the. circuit, wlu-u'eupon threedistinct ellerls are produced first. the indicator corresponding tothat. particular liuois restored (no matter how many other indicationsmay be showing: from other floors at the time) second, the answer barkor return signal is given to.the passenger by the u'ierliauical clickwhich he hears as his button is returned to its normal position understress ol the spiral spring S on the shank (and at the same time theshutter is displayed as indicated on the directions in Fig. third, thecorresponding indication disappears in the other car or cars, thusindicating, to the other conductors that there is no longer need torthem to pay attention to that particularcall.

I It will be noticed, from the construction of the push button boxparts, that the act of pushing the button results electrically in thecontact between the piece ll aud the I spring l and also mechanically 1npermitting the approach of the armature to the poles of the magnet bygravity in the case of a magnet placed the Up button is placed, and bythe aid of the spring K where the armature naturally falls away from themagnet, as in the Down button.) This approach in eith r case is due tothe fact that the lllClllliit-LOII of the cam X is such that as thebutton returns to its normal posihelical spring S, the slope of the camwill force upthe armature while rocking it upon th pivot which supportsit in the frame as shown. This particular motion is of course notessential to the general function of the box, nor is the particular formof box or push button controller which is ehownessential to theoperation. of the invention butthis special form has been illustratedand Selected in the present embodiment of the invention because of thesimple mechanism-required to make it 4 oo-wee possible for a very smallamountof cursrcn'i; vto produce the clutching cllecis upon the to thepole will make ii possible for a current to hold the armature clown inspite of the force exerted upon-iii luicrally the cznn, Whereas iheseine cui'i'enl coulcl no; poesihly energize the magnet sullicicnily loenable the uttruclioi'i upon the arnnziuire to cause the latlci' i0depress lhe bul ion. ll is obvious, limt when in paseengeiwho h pushed ahutfon, ilc ircs to canc the cal ihc bution (tho lan e l he merely pullsO] a of which prevents it from sinking heyom his reach) and, as merelythe slight me neiic alll'uction 21ml {he friction of ihc hni hold it in,a barely perceptible pull will store the billion contact and the normalc1rcuit conditions.
